Ultra-compact pneumatic cylinder with space-saving design (40% smaller than standard cylinders), featuring dual adjustable cushions for precise end-position deceleration control. The anti-rotation rod design ensures stable linear motion, while the multi-layer sealing system achieves ≤0.5mm/s creep speed at 0.5MPa. Compatible with magnetic sensors for position feedback (sensor groove on cylinder body).
- High-density automation cells in electronics assembly
- Precision clamping fixtures for CNC machining centers
- Sorting mechanism actuators in packaging lines
- Medical device positioning systems requiring smooth motion
- Cleanroom applications (low particle generation design)
Installation guidelines:
Maximum side load ≤15% of thrust rating. For vertical mounting,
use counterbalance valves when handling suspended loads.
Lubricate through air supply (Oil mist 1-2 drops/m³).
Allow 2mm clearance around rod for thermal expansion.
